We already knew that General Motors, having announced in early June that something powerful was “hiding” beneath the new hood scoop and new cold air intake system, had something up its sleeve for its 2017 model year heavy duty trucks. Since then, we’ve been
patiently waiting for even the slightest bit of info about the 2017 model year HD trucks. The wait is now (partially) over, since GM’s just-published order guides reveal the complete updates and changes to the 2017 Silverado HD family, which includes the 2017 Silverado 2500HD and 2017 Silverado 3500HD.
First and foremost: yes, that new hood scoop and intake system is, indeed, hiding a new 6.6L Duramax Turbo-Diesel V-8 engine. Assigned RPO code L5P, the new B20-compatible Duramax is mated to the Allison 1000 6-speed automatic transmission (MW7) and is available across all trim levels of the 2017 Silverado Heavy Duty. Quite unfortunately, there are no other details on the new oil burner — like power or torque ratings — just yet.
The base engine in the 2017 Silverado HD remains the 6.0L Vortec L96 V-8. The gasoline drinker is still E85-compatible, meaning that it’s capable of running on unleaded or up to 85 percent ethanol. Like in the previous, 2016 model year, it continues to make 360 horsepower (268.4 kW) at 5400 RPM and 380 pound-feet of torque (515 Nm) at 4200 RPM. The L96 continues to be matched with GM’s 6-speed MYD automatic, electronically-controlled heavy duty transmission with overdrive and tow/haul mode. The gearbox also includes Cruise Grade Braking and Powertrain Grade Braking. On to the other changes.
Three exterior colors are deleted while two new ones are added:
- Slate Grey Metallic
- Autumn Bronze Metallic
- Tungston Metallic
- Graphite Metallic
- Pepperdust Metallic
Rounding out the changes to the exterior are new 20-inch 6-spoke polished aluminum wheels and the aforementioned hood scoop for models with the new Diesel engine. Lastly, capless fuel fill is introduced for models with the L96 V-8 gasoline engine, while the capped fuel fill remains on models with the L5P Duramax 6.6L Turbo Diesel V-8 engine and pickup box delete.
Inside, the 2017 Chevy Silverado HD adds Teen Driver mode and a new Jet Black Medium Ash Gray color combination available on the High Country (3LZ) trim.
On the subject of trim levels, the 2017 Silverado HD continues to be offered in four trim levels:
- Work Truck (1WT)
- LT (1LT)
- LTZ (1LZ)
- High Country (3LZ)
But there are some changes to the equipment within the trims as well as to the truck’s various standalone equipment packages:
- High Country Premium Package is deleted
- The LT trim level gains the rear vision camera as standard equipment, causing it to be removed from the LT Convenience Package as well as the Texas Edition and All Star Edition
- LTZ Plus Package adds the heated steering wheel feature
- A new LPO-level (dealer-installed) Chrome Essentials Package is added, and includes:
- Chrome recovery hooks
- 6-inch rectangular chrome tubular assist steps
- It requires the Crew Cab or Double Cab model and is available only on the LT (1LT) trim level
- For those interested, the Chrome recovery hooks are available as a standalone LPO option on all trim levels
- A new Alaskan Edition package is added and includes:
- 18-inch black aluminum wheels
- LT275/65R18E 123/120Q maximum traction blackwall Goodyear Wrangler DuraTrac tires
- Snow Plow Prep Package
- Smoked Amber roof marker lamps
- Spray-on bed liner
- Unique decal package
- The RPO code of the heated and vented seats changes from KB6 to KQV
We should also note that the 2017 Silverado HD changes and updates are quite similar to those for the 2017 Sierra HD.
Stay tuned as we learn more about the 2017 Silverado HD in the days and weeks ahead. Suffice to say, we will be doing our best to dig up anything and everything we can about the new L5P Duramax diesel engine.
